After installation and device configuration of FMB6 (CAN1 should be selected – FMS/TACHO), you can check if the installation is properly made. Turn on the ignition of the vehicle and send SMS command: “tachocheck”. If the response shows: “Can1:111,F2EF”, 111 -means tachograph properly connected, F2EF - or any other value which is not equal to 0000, means FMS data received also.
